“The action was taken as a result of a command-directed investigation,” Cadwell said in a statement provided to Air Force Times. “I lost confidence in Colonel Hamilton’s ability to lead the group and Lieutenant Colonel Olson’s ability to lead the squadron.”

Hamilton and Olson are not under criminal investigation, and their removals are not connected, according to the statement.

Col. Brian May, 501st Combat Support Wing vice commander, replaces Hamilton as group commander until a permanent replacement for Hamilton arrives this summer.

Maj. John Riester, 423rd Communications Squadron commander, will temporarily replace Olson. No permanent replacement has been named yet.

A wing commander may relieve a subordinate commander of duty for reasons he or she deems appropriate. “My primary focus is the health, welfare and organizational climate of this wing,” Cadwell said.

The 422nd Air Base Group, headquartered at RAF Croughton, provides combat support enabling communications and global strike operations at RAF Croughton, RAF Fairford and RAF Welford, according to the Air Force. It is made up of approximately 600 people.
